TAP.

Specification of Letters Patent.

Patented May 19, 1914.

Application filed March 26, 1912. Serial No. 686,323.

To all whom it may concern:

Be it known that 1, WILLIAM ALnxaNnnR FRASER, of the town of Georgetown,1n the county of Halton, in the Province of Ontario, Canada, haveinvented certain new and useful Im rovements in Taps, of which thefollowing is the specification.

My invention relates to improvements in taps or faucets, andthe objectof the invention is to devise a simple, efiicient, cheap, durable andreadil operated tap or faucet, which will not be iable to get out oforder and in which all danger of leakage due to continual use isabsolutely avoided or readily' provided against.

A further object is to provide a tube in which the vital arts viz. theseat and valve will be removab o with a minimum amount of trouble and ata minimum cost.

My invention consists of a tap comprising a main body having a. centralenlargement and cross boss in front of the same, a dependin removablespout screwed into an orifice at t ebottom of the body and provided witha seat at the top a ball restingon the seat, a stem extending throughthe hollow boss and provided with a substantially crank-shaped inner endor blade fitting at the extreme end into a limiting recess in the bossof the body, the parts being otherwise constructed and arranged ashereinafter more particularly explained.

Figure 1, is a perspective view of a tap constructed in accordance withmy invention. Fig. 2, is a vertical section through the main portion ofthe body showing the spout mostly in full. Fig. 3, is a cross section atright angles to the section shown in Fig. 2. Fig. 4, is a detail of anend of the base in section. Fig. 5, is a section similar to Fig. 2,showing a stem handle self-restoring to the normal position.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is the main body of the tap, which has a pipe extension A leading tothe source of supply and having a flange A for supporting the tap.

A isa cross hollow boss threaded at the one end and provided with anorifice A and at the opposite end provided with a sectoral recess A B isa spout, which is provided with a nutlike portion B and a threaded upperend B which is screwed into the internally faucet havin bottom threa edorifice, of a spout screwed threaded orifices A at the bottom of thebody portion.- 1

C is a ball, which may be made of rubber, brass or any suitablematerial. The ball 0 rests on a seat B at the top of the spout B.

D 15 the operatin stem, which is provided with the usual andle D and theenlargement D and the cranklike blade D which extends at the inner endinto a sectoral recess A, which serves to limit the throw of the tap toabout a quarter turn or slightly less. The enlargement D abuts thethreaded end of the hollow boss A and may be provided with a washerbetween it and the hollow boss.

E is a screw cap provided with a nutshaped periphery at the outer end,which is screwed on to the threaded end of the boss A and thereby servesto hold the stem 1n position.

In Fig. 5 I show a spiral spring 2 located between annular shoulders 3formed on the stem D. In this form of faucet one end of the spiral sprinis connected to the body and the other to t e stem, and thereby when thehandle is operated as hereinafter described the sprin serves to restorethe handle to the norma position.

The operation of my faucet is simple and is as follows: The handle D ispulled down and the blade D is thrown into the position shown in dottedlines in Fig. 3, thereby throwing the ball away from Its seat andallowing the liquid to pass through the spout B. By throwing the bladeinto the position shown in full llnes in this figure the ball is causedto resume its seat.

From this description it will be seen that I have provided a very simplefaucet in which the valve is quickly removed from the path of the waterand is not subjected to variable pressure so as to cause it to bound onits seat, but is held in such a position as to be readily and quietlyoperated both toremove it from its seat and restore it to its seat whenthe desired amount of water is withdrawn.

What I claim as my invention is:

1. The combination with the body of a a central enlargement and into theorifice and forming a valve seat, a ball resting, on the seat, a valvestem having a blade at the inner end of cranklike form,

the central enlargement having a boss in which is located at sectoralopening into which the end of the blade extends as and for the purposespecified.

Q. The combination with the valve body having :1 central enlargen'ientand cross hollow boss and the spout depending from the body and having aseat formed at the top, of a ball resting on the seat, a valve stemhaving a blade off-set and ascrew cap for the end of the boss throughwhich the valve stem extends as and for the purpose specified.

8. lhe combination with the body of a faucet having a centralenlargement and
